Those scores would be applicable to the performance in W10, but Microsoft did not include the Windows Experience Index built-in speed testing the same way after W7. So, I can only give you these scores when I test a workstation running W7. The WEI scores, however, have been very handy in that I can load W7 pretty quickly, without loading all the other software I'd load on later, and get baseline performance scores easily. In our experience those do translate over into the real world perceived differences workstation to workstation.
Here are a couple pics for you.
At the bottom of the Z400 backplane is an eSATA backplane adaper.... for me having access to the SATA bus without having to open the case is quite handy. That is plugged into the last SATA port, and in BIOS you can set it to eSATA standards. Next up is the old HP Oxford chipset PCI card that lets me still use some special parallel port devices. That card has W7 drivers.... not sure about W10 drivers yet. Next.... this "blower" type of video card pulls air in from the case and exhausts that out the rear backplane area of the Z400. For that reason I've not felt compelled to add a front case fan yet. The rear exhaust thus is via the power supply, the rear case fan, and the blower in that video card. Note my addition of the 40x40x20mm fan to the Northbridge heatsink, with its Noctua 4-wire fan speed reducer added which plugs into the motherboard's PWM header barely visible to the right:
I've yet to add in my HP Texas Instruments based USB 3.0 card, but with the HP 3.5 to 5.25" adaper and the Akasa front interface it will look like the lower picture, from a Z600 build. I'll install that right under the optical drive:
